I accidentally damaged the circuit board

WT All Messages By This Member #20842 开云体育 Yes you can. ? Clean the area with IPA and scrape away the green laquer to expose the copper trace. ? Solder a Wire between the two pins of the battery. ? However, you must check the PCB on the component side to check which pin is used to connect to the rest of the circuitry. ? WT ?

Hello everyone. After reading that article on replacing the battery base for the machine, I tried to replace the battery base myself, but due to my poor soldering skills (first time using it), I accidentally burned the solder joint in the negative battery hole, making it impossible to adsorb solder now. Can I connect a wire from the right solder post and run it through the negative hole of the battery? Thanks to all the experts for their input.
Bruce Wahler #20843 开云体育 Yes, you can connect a wire in place of the circuit board trace.? At the most fundamental level, that's what a circuit board trace is, a thin wire.? As long as the wire does not touch any other traces when you are finished, it will work. Two comments: WT's suggestion to use what's left of the trace as a "pad" is a good one.? This creates a new connection for the repair wire, which may be beneficial for the future.? Use a sharp, pointed knife like an X-Acto #1 to scrape 4-5mm of the green coating from the damaged trace near the 'burned' end.? Use light force; you do not want to cut through the copper.? The exposed copper can then be used as a soldering point for the new wire. If you are new to soldering, I would recommend practicing on some other, less valuable circuit board a little before you proceed.? Also, do not use a fixed-temperature iron of more than 25-40W.? Better yet, use an iron with an adjustable temperature control.? I see dozens of them on Amazon for less than $50USD.? You only need about 200C to melt lead solder, and about 250C to melt tin solder.
